Testador de circuitos Ancel PB500 – testador de tensão e continuidade para eletricidade automóvel

The Ancel PB500 is a compact circuit tester for 12–24V vehicles and equipment. It provides seven diagnostic modes including AC/DC voltage measurement, resistance and diode testing, frequency and duty cycle checks, and injector circuit testing. A color TFT display shows parameters in real time to help locate faults faster while the device remains portable and easy to handle.

Advantages

The tester covers a wide operating voltage range, making it suitable for cars, trucks, motorcycles and boats. It combines multimeter-like measurements with dedicated automotive tests to detect short circuits, open circuits and grounding issues without dismantling the installation. Built-in overload protection helps prevent damage from incorrect connections, and a probe tip LED improves visibility in poorly lit or hard-to-reach areas.

How to use

Connect the battery cable to the vehicle battery or power source within the specified voltage range, select the desired diagnostic mode using the device buttons and apply the probe to the test point. Read measurements on the color TFT display in real time and switch modes if additional checks are needed. Use the injector test mode to measure injector voltage and pulse width; use the diode and resistance modes for component verification. Observe polarity and connection instructions from the manual to avoid incorrect wiring.

Recommendations

For safe and accurate results, use the Ancel PB500 within the specified operating temperature and voltage ranges, follow the included manual for correct probe connections, and ensure the vehicle power is handled according to manufacturer guidelines. Regularly inspect test leads and the probe tip for wear before use.
